LE CORBUSIER’S APARTMENT-STUDIO : 3D MODEL DATA OF PRELIMINARY RESEARCH FOR THE RESTORATION

Abstract. Fondation Le Corbusier and A-BIME have collaborated to collect, analyse and organize preliminary research data for the restoration of the Le Corbusier’s apartment-studio in Paris using a methodology based in a 3D model. This work, developed by A-BIME since 2014, has been financed by Fondation Le Corbusier thanks to a “Keeping it modern Grant”, giving by the Getty Foundation. The aim is to have faster and easier access to various data of the building by using a clear and documented digital graphic document.

For each step, the archives provided by the architect and the companies have been studied to understand and know the nature and quality of materials, technical arrangements and their on-site implementation. A study on technical installations and isolation as be provided as well by investigation in the apartment. By switching between the documents and the images, the know-how increases along with the development of the 3D model; the architectural elements have been drawn and modelled from the archive data and from the survey and diagnostic phase.

The numerical construction, based on precast elements, follows the pioneering efforts of specialized architects with the BIM (Building Information Model) technology. Thanks to the .IFC format the model has been imported in several software in order to proceed structural and hydrothermal simulations. The results have been used has guidelines by the Fondation Le Corbusier to forecast the consequences of restoration choices.
